Appnation :meu Novemter To @ZZ 'whom t may'concern. Y v Be it known thatI, JOHN F'Ilrnorl OSCAR- soN, a citizen of the 'United States, residing`checks, of which theffolloiving is a specification, reference being hadto the accompanying ,drawings This invention relates to door checks, andmore partieularlyto .that type of strap door check vemployedfor-limiting the openinggof the-door particularly withs'auptomobiles`and the like; Y

An important object' of the invention is to Aprovide in .a device. of:this character a construction such that sudden' checking :of themovementlof the'door, when the door reabhes its limitvof movement asdefined rby the strap, is prevented, thus removing from the door anddoor post and the connections therebetween the strains to which they areordinarily subjected.

A further object of the invention is to provide a device of thischaracter which may be applied by anyone to the door without the use ofany other tools than a screwdriver, and in which the application to thedoor may be made without marring the surface of either the door orframe.

These and other objects I attain by the construction .shown in theaccompanying drawings, wherein for the purpose of illustration is showna preferred embodiment of my invention and wherein Figure 1 is aperspective view showing a door check constructed in accordance with myinvention applied to a vehicle door;

Figure 2 is a sectional view through the yielding member of the check.

Referring now more particularly to the drawings, the numeral 10indicates a strap of any suitable construction but preferably of someinextensible or substantially inextensible material, such as heavyleather or rubberized canvas fabric such as is ordinarily employed inconstruction of drive belts. @ne end of this strap is provided withmeans, as at 11, whereby it may be secured to the vertical post 12 of adoor frame, consisting in the present showing of a cleat about which oneend of the strap 10 is securedvas at 13.

To the door proper is secured a metallic body 14 having openings 15therethrough through which the securing elements may be semi No.748,624,

extended" tioattach' the body tothe door. The y body extendshorizontally-of the door and is provided with' a Vpair of'spacedparallel longitudinally extendii'ig bores v'16 opening' throi'igh oneJend of "the cylinder; Opposite 4end ofthe cylinder' reduced bores 17communicate' with 'the inner endsof the bores 1G.-y Through 'thesereduc-'ed bores`17 are extended arms 1Scf a U-s'haped strap clip, saidarms having *their extremitiesthreaded and provided 'with nuts 19.: Bei`tween these nuts 191 'and the inner end walls of the bores v167springsffZO"surround the arms 18' and tend to urge .the 'bigh't portion"this bight portion and secured, as at 22.

The strap 10 in' the construction thereof is made of such length that itwill of itself permit opening of the door only to a distance less thanthe normal amount of opening of the door. In other words, this strap ofitself limits the movement of the door prior to the complete openingthereof. lVhen the door arrives at the limit of its movement as definedby the strap, tendency of the door to continue in its movement willplace a strain against the U-shaped member causing the arms of the sameto shift` longitudinally in the bores 16, so that the springs 2O arecompressed between the nuts 19 and the inner end walls of the bores 16,thus applying a lcushion to act as a final check of movement of thedoor. VStrain is thus removed both from the fastenings of the cleat 11and the metallic member 14 as well as from the hinges of the door andthe frame and post thereof. It will be obvious that a strap of fixedlength suddenly limiting movement of the door would tend to rack theframe of both the body to which one end ofthe strap was secured and thedoor to which the opposite end was secured.

Since certain changes and modifications may be resorted to in theconstruction of the strap without materially departing from the spiritof my invention, I do not limit myself to such specific structure ashereinbefore set forth except as hereinafter claimed.

I claim 1. Means for yieldably checking movement of a door with relationto the door post thereof including a strap secured at one end to onethereof, a metallic body At nthev secured to the other thereof andhaving a pair of spaced parallel bores, a U-shaped member having itsarms directed into said bores, springs engaging the arms of the U-shapedmember' and urging the arms in such direction as to urge the bight ofthe U-shaped member toward the metallic body, and a connection betweenthe bight andthe metallic body and the opposite end of the strap.

2. Means for yieldably checking movement of a door with relation to thedoor post thereof including a strap secured at onel end to one thereof,a metallic body secured to the other thereof and having a pair of spacedparallel bores, a U-shaped member having its arms directed into saidbores, springs engaging the arms of the U-shaped member and urging thearms in such direction as to urge the bight of the U-shaped membertoward the metallic body, and a connection between the bight and the'metallic body and the opposite end of the strap, said metallic bodyhaving a central` portion located intermediate the portions of the bodyin which the bores are formed which is reduced and provided withopenings for the reception of securing elements.

3. Means for yieldably checking movement of a door wit-h relation to thedoor post thereof including a strap secured at one end to one thereof, ametallic body secured to the other thereof and having a pair of spacedparallel bores, a U-shaped member having its arms directed into saidbores, springs engaging lthe arms of the U-shaped member and urging thearmsin such direction as to urge the bight of the U-shaped member towardthe metallic body, a connection between the bight and kthe metallic bodyand the opposite end of the strap, the bores of said metallic bodyopening through one end of the body and at the opposite end of the bodybeing reduced, the arms of the U-shaped member being introduced to thebody through such reduced openings, the springs extending intermediatethe shoulders formed vat the last named ends of the bores, and nutscarriedl by and adjustable upon the extremities o-fV said arms Intestimony whereof I hereunto affix my
